摘要：
The magnetization, magnetic susceptibility, and specific heat of heliumlike confined quantum dots are calculated. The Schrodinger equation for the relative motion of the two electrons is solved numerically and the solutions are used to calculate the partition function. We found a sharp peak in the susceptibility and an additional structure in the specific heat. The correlation energy and spin contribution are shown to be important.
